Hello!
I have a question,could you please give an idea about how can I calculate an inversed Z transform of these ( Z^(-1)[...] ) :
z/(z^2+z+1)
and
z^2/(z^2+z+1)
Thank you in advance.
You should probably factorize.
Also you may refer to Mathematica 7.0 - InverseZTransform.
As a little note, if , then we can not find an exponentially bounded sequence for which [tex]f(n)=Z^{-1}\{F(z)\}(n)[\math] holds.
